BROOM-MACHINE.

- Application filed November 25, v1910.

T0 all 'whom t may concern.'

Be it known that I, FREDERICK W. REESE, a citizen of the United States,and a resident of Paris, county of Edgar, and State of Illinois, haveinvented certain new and useful Improvements in Broom-Machines, of whichthe following is a specification.

My invention is an improvement in broomv machines, and consists incertain novel constructions and combinations of parts, hereinafterdescribed and claimed.

The object of the invention is to provide a simple, easily operatedmachine of the character specilied, for holding a broom handle duringthe formation of the broom, wherein a normally operative gripping deviceis held in inoperative position by a latch or other means, which isreleased by the insertion of the handle into the machine.

Referring to the drawings forming a part hereof, Figure 1 is aside viewof the improvement. Fig. 2 is a vertical section of the improvement, onthe line 2 2 fof Fig. 1,

with the parts in one position. Fig. 8 is a' similar view with the partsin another position. Fig. 4 is an end view of the barrel. Fig. 5 is asection on the line 5 5 of Fig. 3, Fig. 6 is a detail perspective viewof the case and shell, and Fig. 7 is a section on the' line 7-7 of Fig.2.

The present embodiment of the invention comprises a case 1 ofcylindrical shape having one end beveled at 2 and provided at the otherend with a cap 3. The'case is supported in a sectional bearing 4,1on thetop of a standard 5, and the sections of the bearing are held togetherby bolts 6. 'Ihe cap 3 is provided with a transverse slot 7, and a shell8 is slidable in the case and is moved by means of a yoke having a bodyportion 9,

and arms 10. The yoke is slidable through Vthe slot 7, and the arms 10are secured to the shell by rivets 11. A coil spring. 12 is arrangedbetween the cap and the adjacent end of the shell, and acts normally topress f the shell away from the cap. A collar 13 encircles the caseadjacent to the bearing 4, and a sleeve 14 is slidable on the oppositeend of the case from the collar, and is normally pressed away from thecollar by a coil spring 15 which encircles the case between the col! larand an annular rib 16 on the sleeve. The sleeve is provided with ankannular enlargement 17 at the end remote from the rib,

forming an annular channel 18 at the end v of the sleeve, and adjacentto the channel-the Specification of Letters Patent.

Serial No. 594,078.

inner surface of the sleeve is provided with oppositely arrangedrecesses 19.

The case 1 is provided in its wall with oppositely arranged slots 20,and a latch 21 is pivoted at 22 in each slot. Each latch is providedwith a cross head 23, and in certain positions ofthe shell, the crossheads are adapted to be received in the recesses 19. lhen the shell andthe sleeve occupy the position of Fig. 2, the latches are in theiroutward position, the heads 23 thereof being received in the recesses 19of the sleeve, andk the latches hold the sleeve from movement toward thebarrel. `When the sleeve is moved toward the barrel, the heads areforced inwardly. Before they can move inwardly, however, the shell 8must first be moved toward the collar, in order that the heads 23 of thelatches may be engaged with the end of the shell, as shown in F ig. 3.A. barrel 24 is `arranged in alinement'and integral with kthe case, andthe said barrel is supported in a sectional bearing 25, on the upper endof a standard 26. The sections of the bearing are held together vbybolts 27. rlhe barrel is provided with a reduced portion 28 for engagingthe bearing and outside of the bearing the endk of the barrel istapering as shown at 29 in Figs. 1, 2 and 3.

A plurality of jaws 30 are arranged in the tapered portion, in spacedrelation, each jaw having the face adjacent tothe wall of the barrelinclined as shown at 31V to fit the said wall, and each jaw is providedwith a stem 32. Each of the stems extends through an opening 322tbetween the barrel and the case, and the free end of the stem isprovidedl with a lateral lug 33, which is received in the channel 18 ofthe sleeve 14. lVhen the sleeve 14 is moved longitudinally,

the jaws are moved longitudinally of they tapered portion of the barrel,and the en? gagement of the outer inclined face of the jaws with thetapered surfacer of the barrel, moves the said jaws inwardly. The innerfaces of the jaws are curved transversely,

as shown at 34 in Fig. 4, to fit the outer face of the broom handle 35,and the j aws firmly clamp the handle to prevent any rotary movementthereof.v A curved bracket arm 36 extends laterally from the bearing,curving toward the sleeve 14, and a lever 37-is pivoted to the arm at38. The free end of the lever is provided with agrip 39, and thelever'is connected to the sleeve 14 between the rib 16 and theenlargement 17. The inyPatented. Mar. 9, 1915.

lic

ner end of the barrel is provided withan annular series of spaced radialteeth 40, and the inward movement of the shell 8 is lime ited by laterallugs 41 onthe arms 10 kof the yoke.

cated yinFig. 1, to permit the passage of the handle, andan ejector inthe form of a rest or stop 42 is provided for engagement by the end ofthe handle. The rest or stop is in the form of a block centrallyrecessed to lit the end of the handle, and isl held on the yoke arms bymeans of a loop 43, encircling the arms,`and held in adjusted positionby a set Screw 44. f Y

The inner or engaging faces of the jaws arev preferably corrugated togrip the handle more firmly. The said jaws are normally pressed intogripping position by the spring 15, which presses the sleeve toward thebarrel. They may be locked in open position, byy the shell 8, asindicated in Fig. 2..

In operation, withthe parts in the posif. tion shown inFig. 2., thehandle is inserted, until the `end thereof engages the stop, 42,y

and presses the said stop toward the right of Fig. 1. The shell is thenpressed toward the cap, 3, until the latch -heads are free to moveinwardly. As soon as this occurs, the

sai-.fl heads hold the shell from reverse movement. yThe inward movementof the latches also 'releases the sleeve; 14, which is then pressedtoward the barrelby the spring .15,

. and the 30 are pressed into close gripping relationrwith the handle.'.lhe stems 32 are resilient, and constrain the jaws to followthe innersurface of the tapered part of the barrel, so that as the said jaws areVmoved inwardly, theyy also movey radially away from the handle.

To. release the handle, the lever 37 is moved to the position shown inFig. 2, thus .moving the sleeve toward the collar, againstv theresistance of the spring 1,5. The jaws are moved into the barrel andaway vfrom the handle, and when the'sleeve is in the position shown inFig. 2 thespring 12 forces thev shell toward the barrel, moving thevlatches outwardly, into the recesses 19, and locking the sleeve in theposition shown in Fig. 2. The inwardv movement of the shell is limitedby the lugs 41. Therdevice is rotated by a sprocket chain'engaging theteeth 40. of the barrel.

rljhev barrel and the case, as before men-v tioned, ,are integral 'with'each other, but theL barrel` is connected with the case by means-l ofka shoulder and openings 32a,^through which'the stems extend, areprovided in the said shoulder.` .v

- The devicewill 8", the spring 1,2, the yoke-9,410, and the latch 2 3.The above mentioned parts. are

merely for locking the gr-lfrrllav jaws in` open orV closedAY position.,The chief strain The handle 35 extends through the slot v7 which isenlarged` at its center as indi-YV operate without the shell of the wirebeing wound thereon.

n Fig. 1 is shown a means for automatically releasing the handle. Thesaid means comprises a shaft 50 journaled on the stand.- ards 5 and 26,and provided at its outer end Vwith a pulley51 by means of which it ymaybe'vrotated. -A bracket `52 is arranged between the standards vandalever Y53 is pivotf ed at 54 on the said bracket. The upper end of thelever is forked at 55., and the armsA of the fork engagethe grooveformed between the channel 17 land the rib 16. The opposite end of thelever is provided with an angular Portion 56, which is adapted forengagement with a pin 57 kon a disk 58 secured to the Shaft 50. Y

It will be evident that whenthe .shaft 50 is rotated by means of thepulley 51, the lever 53, will he osollated to intermittently move thesleeve. in Vthe opposite direction from the barrel, wlgierebyv torelease the gripping jaws. This construction, it will. be understood,will replacethe operating mecha-V nism comprising the bracket and handle37 shown in Figs.v 2' and 3. A second lever 60 is pivo-ted at Glicn theendof the bracket shaft 50 is the power shaft, and is connected tothebarrel bya belt 67 which connects a pulley 68 on the shaft 50withapulley 69. on the barrel, the said pulley taking the place of thesprocket teeth showny in Figs.l 2 `and 3. Y

The construction ofthe .broom makingV machine propershown'inv Fig. 1 is`precisely the samel as thatV shown in Figs. 2 and 3.

The formerk construction is, however, a

power machine, while Athe'latter is a hand machine. After thebroom hasbeen completed, thesleeve 14 is 'moved toward thev ,bearing v4.y Thismovement releases the gripping j awsl from the handle, and when.

the sleeve is in such position that the heads 23 of the latches mayenter the recesses 19 of the sleeve, the shell 8 is released and the 12forces the said shell. toward the springV jaws. The stop 42 is also.forced toward the jaws and the. completed broom is lejected from themachine.

The bracket 52 in Fig. 1y is movable longi- 'tudinally,l ink order thatthe levers 5.3 yand 60 may be shifted into and out. of engagingposition. During thewinding of the wire on vthe, broom, the 4bracket isshifted tomove the levers out of engaging position, in order that thegripon the broomy handle maybe retainedthroughout the winding operation.

-iio

After the broom has been wound, the bracket Y 52 is moved awayV from thebarrel, to bringv therleversv 5.3,A and 6.0;y into position foren-vgagement by the pins of the respective disks. The pin on the disk 58 isin advance of the pin on the disk 66, so that the lever 58 is firstoperated to place the parts in the position of Fig. 2. The upper end ofthe lever is swung away from the barrel, thus moving the sleeve 14 awayfrom the barrel, and moving the gripping jaws toward the large end ofthe portion 29 of the barrel, to release the broom. As soon as the broomis released, the spring 12 expands ejecting ther broom from the barrel,and a new broom is immediately inserted. The pin of the disk 66 nowengages the lever 60, and moves the upper end thereof away fromthebarrel, thus placing the parts in the position of Fig. 3, and causinglthe gripping jaws to clamp the new broom and hold it for winding. Thebracket 52 is longitudinally slotted, as indicated at 52a, and the pin62 moves in the slot, to permit the longitudinal movement of the saidbracket.
